Rényi security framework against coherent attacks applied to decoy-state QKD
Lars Kamin, John Burniston, Ernest Y. -Z. Tan
We develop a flexible and robust framework for finite-size security proofs of quantum key distribution (QKD) protocols under coherent attacks, applicable to both fixed- and variabl…

Necessary and Sufficient Conditions on Measurements of Quantum Channels
John Burniston, Michael Grabowecky, Carlo Maria Scandolo +2
Quantum supermaps are a higher-order generalization of quantum maps, taking quantum maps to quantum maps. It is known that any completely positive, trace non-increasing (CPTNI) map…
